Our take...

What can have been going on? Were bin Ladin and Bush discussing the coming attacks over some secret breakfast, just the two of them? Find out a little more about this meeting and it seems unlikely.

Like everyone else in the United States, the group stood transfixed as the events of September 11 unfolded. Present were former secretary of defense Frank Carlucci, former secretary of state James Baker III, and representatives of the bin Ladin family. This was not some underground presidential bunker or Central Intelligence Agency interrogation room. It was the Ritz-Carlton in Washington, D.C., the plush setting for the annual investor conference of one of the most powerful, well-connected, and secretive companies in the world: the Carlyle Group...

Carlyle emerged from the shadows in spite of itself on September 11, 2001. That day, the group had organized a meeting at Washington's Ritz Carlton Hotel with five hundred of its largest investors. Frank Carlucci and James Baker III played masters of ceremony. George Bush senior made a lightning appearance at the beginning of the day. The presentation was quickly interrupted, but one detail escaped no one. One of the guests wore the name bin Ladin on his badge. It was Shafiq bin Ladin, one of Osama's many brothers.

So "George Herbert Bush met with Osama bin Ladin’s own brother" would seem to be more accurately described by saying they were both at the same meeting, along with hundreds of other people. Did they actually meet in person? Bush senior was reported to leave early ( see above and http://www.thirdworldtraveler.com/Bush_Gang/CarlyleGroup_TETTR.html ) so there may have been little opportunity. Doesn't prove they didn't, of course, but if you think they did then show us the evidence: misleading quotes are not enough.
